Published in IEEE
Multilevel converters are the result of growing need for higher power converters. This paper presents a new configuration of stacked multi cell converter using PWM technique controlled by fuzzy logic. The main advantage of this new configuration of stacked multi cell converter in comparison with other multi cell converter is reduced number of DC voltage sources. Here in this paper the number of DC voltage sources is reduced from two to one. We can achieve this by connecting upper stack switches by a common DC voltage source. By increasing the number of levels the ac output with fewer harmonic is achieved. As the number of levels increases the output voltage is improved and simultaneously THD (Total Harmonic Distortion) is reduced. In this paper THD is controlled using MAT LAB/fuzzy logic tool box. The circuit in this paper is simulated using MATLAB/SIMULINK and the results are presented to check the effectiveness of the converter and its control. © 2014 IEEE.
